I am not struggling with eating out of boredom YET, but I understand exactly what you are going through as I have done this my entire life. Planned snacks are great, and the nuts or jerky can fit into that plan. The key is having the mindset that the snack is fueling your body instead of just doing it because you are bored.
I smoked cigarettes for 10 years. When I quit 10 years ago, I realized that "triggers" as they call it, were real. I mentally and unconsciously had a cigarette whenever a trigger was present. That trigger might be getting in the truck to drive. It might be the end of a meal. The point is that if you are snacking when you are bored, you are continuing the bad habit that got you into trouble in the first place. I think this is a big problem for most of us. We have to use this time to change that if we are to continue being successful.
I work at a computer all day. I got my job to purchase a Veridesk for me, so that I can stand up and work. It does help. It takes me out of my comfort zone of sitting, and the cravings dissipate. I also burn more calories standing than sitting. Mind you, I don't do this all day. Just periodically. Maybe you can take a break and walk around the office for a minute or two whenever you get that craving.
You are doing really well, and I have no doubt that you will continue to be successful. Mindless snacking might just be the thing that hinders you from meeting or exceeding your goal weight as the weight loss will undoubtedly slow down in the coming weeks and months.
Anyway, good luck and thanks for bringing this up. This is a topic that is a real problem for most of us.
